Repairing AGA Center brace

[Cazoom]

is it cracked or melted?
i got my 90 gal with a melted brace..funny almost could make out the bulb shape..old owner must have no sense of smell...

pulled out the soldering iron.. made a flat tip.. and remelted it till it looked ok....
same thing we do to car bumpers that crack....
when you don't know what to patch with, use parts of the original...little razor scraper to take off pieces and fill in bare areas...
just watch the heat dont burn it...just soften it till its moldable ...
